Invisibility Cloak

Posted: 16th June 2011 by 7ucyClark in geek stuff, tech

Metamaterials are ‘fabrics’, the weave of which is composed of structures smaller than the wavelength of light.  The upshot is that this material can bend light, effectively making a piece of metamaterial a swatch of Invisibility Cloak.  Except that no one had been able to create the material in any kind of usable area.
Til now, of course.  John Rogers, a professor of materials science and engineering at the University of Illinois at Urbana-Champaign, has found a way to ‘print’ the material via stamping process.

“So far Rogers says he’s made metamaterial sheets a few inches per side, but by using more than one stamp he expects to increase that to square feet. And, he says, the stamped materials actually have better optical properties than metamaterials made using traditional methods.”

Eventually, as this settles into the technology/cost nadir, cloaking devices are going to be available at Walmart for $19.95.  And when that happens?  High School girls locker rooms are going to need biometric security scanners.
